I was hoping that worcmik would answer. Tatnuck burying ground no longer exists. The burials and stones were removed to the St. John's Cemetery and other places depending on the wishes of the families. This was done to create more area for development. Don't get me going! Tatnuck was the first consecrated ground in Worcester for Catholic burials. Some very poor irish people were interred there some with only wooden crosses, according to Richard O'Flynn the irish historian who transcribed the cemetery before its demolition. Please correct me if I'm wrong, worcmik or anyone else.
I think that the burials are on a database under projects if you want to see them at tiara.ie.
